METHOD OF MAKING HONEYCOMB BRICK Filed Aug. 17, 1929 gwomkw Patented Jan. 12, 1932 UNITED STATES BENJAMIN A. SCHNEIDER, OF LAUREL, MISSISSIPPI METHOD OF MAKING HONEYCCMB BRICK Application filed August 17, 1929. SerialNo. 386,679.

This invention relates to improvements in the manufacture of building construction materials such, for example as bricks or blocks composed of clay burned to the desired hard- 5 ness, the primary object of the present invention being to provide an improved method of forming a hardened face for brick which is practically impervious to water.

'A further object of the invention is to provide an improved method of hardening faces of brick, the carrying out of which will, at the same time, impart a perforated or honey combed face to the brick, giving the same a design different from anything heretofore produced.

The invention will be best understood from a consideration of the following detail description of the steps for carrying out the method taken in connection with the drawings forming a part of the present specification, with the understanding, however, that the invention is not confined to any strictconformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention, as expressed in the appended claims.

In the drawings Figure 1 shows in perspective a brick treated in accordance with the present invention.

Figure 2 is a section through a portion of the brick upon the line 2-2 of Figure 1 showing the pockets formed therein.

Figure 3 is a section similar to Figure 2 showing the condition of the brick before firing.

Referring more particularly to the drawings the numeral 1 indicates generally a brick treated in accordance with the present inven tion, Figure 2 thereof showing a section of a treated face setting out the pocketed character of the same, the pockets being indicated by the numerals 2.

In carrying out the method embodying this invention, after the formation of the brick in the usual manner and from the usual clayey material, the faces to be hardened and honeycombed, as for example the faces 3 and 4: of

the face of the brick forming the area 5 which is materially harder than the burned clay port1on and it is materially less pervious to water.

In addition to the fusing and spreading of the slag particles through the face of the brick, some of the particles burn out, leaving the brick face-pitted or honeycombed, as indicated by the numerals 2.

In Figure 3 there is shown a section of a brick showing the condition of the same after application of the slag particles thereto but before burning, the condition following the burning being shown in Figure 2, showing the depth of penetration of the fused slag. V

The area penetrated bythe slag is indicated by the numeral 5 and this area of the brick is, as previously stated, materially harder and less absorbent than the burned clay. I

While I have particularly shown the slag as applied to the surface of the brick, it is, of course, to be understood that I do not wish to be limited to its use in this manner, for it may be incorporated with the brick clay if desired, before the brick is formed so that after the formation of the brick the slag will be disposed therethrough and will, burn in the body thereof when the brick is fired.

Having thus described my invention what- I claim is 1. The herein described method of forming a decorative surface upon an argillaceous body which consists in embedding particles of slag in the surface to be decorated then burning the body to fuse the slag particles therein.

2. Theherein described method of forming a brick having a pitted, honeycombed surface which consists in embedding particles of slag into the face of the formed brick before burning and then burning the brick to fuse said particles and burn out some thereof, said fused slag running over and penetrating the surface of the brick body to render the same less pervious.

3. The herein described method of forn ing a decorative surface upon an initially plastic body, which consists in embedding in a face of the body particles of fusible material, then burning the body to harden the same and to dissipate the particles, said particles permeating the surface of the body and being of a nature to impart a vitreous finish thereto, the fusion and dissipation of the particles leaving pits in the face of the body.

In testimony whereof I hereunto afiix my signature.

BENJAMIN A. SCHNEIDER.
